To all whom it may concern.'

Be it known that l WALTER Moms, subject of the King of rreat Britain and lreland, residing at y79 Cobar Street Dulwich e Hill, near Sydney, New South tralia, have invented new and useful limprovements in an lmproved Hinge for Vehicle Doors, of which the following is a specification.

rllhis invention relates to concealed hinges for automobile rand other carriage doors, and it consists in making such hinges demountable at the knuckle, with the object that the doors may be removed from w the vehicle without disturbing the fastenf ings by which either leaf of the hinge is tired to the framev post and to the door stile respectively. The particular mechanical arrangement used permits the use. of any 2@ standard form of the boxed hanging leaf which is adapted to be inset in the frame post, with the pintle pin permanently red in it, and it furthermore ensures connection of the leaves through the knuckle without looseners consequent on the provision for the detaching of the cranked swinging leaf from the boxed hanging leaf.

According to the present invention the eye piece of the knuckle is permanently carried on the pintle pin and is armed with a stem piece :odset at 'right angles from its axis. ln the cranked portion of the swinging leaf a hole is drilled' to receive this sternl piece and the end of the crank is recessed to embrace the eye piece. A nut housed` in a countersink in the stem hole engages the stem piece and secures the swinging leaf to the knuckle eye. This nut heing secreted in the countersink, though accessihle therein, is not a disgurement and is practically unobservable. When it is freed the cranked swinging leaf may be drawn o the eye stem to demount the door from the frame.

According to lthe present invention, the intle pin is fixed in the recess of the post eaf, and the hanging leaf is mounted on the pintle pin by a. knuckle which is detachably fixed in the hanging leaf.

Figo is a horizontal sectional view cor'- responding with F ig. l and showing the door swung open; and

Fig. 6 is a vertical sectional view on the line 6 6 of Fig. 5. i

rlhe hanging leaf is of the usual boxed form shown in Fig.` 2, adaptedto be inset in a recess formed for it in a'door post or equivalent portion 10'of a vehiclebody, by means of screws .inserted through the flange holes 11. 12 are holes in which the ends of the pintle pin 18 are mounted. The swinging leaf (Fig. 3) is flanged and holed at 13 for fastening screws by which it is fixed to the hanging stile of the door. The swinging leaf is cranked at 1l, and theend of the cranked portion 15 is. recessed at 16 to form a seating for the'knuckle eye 17, through which the pintle pin 18 passes. The knuckle eye 17 is armed with an' offset stem piece 19 which is accommodated in a hole 20 drilled through the cranked `portion 15 of the swinging leaf (Fig. 3). The outer end of the holes 2O is counterbored as shown 35 at 21 to accommodate a cap nut 22 which is adapted to be screwed on to the'end 23 of the knuckle stem 19. ln setting up the hinge, the knuckle 17 is setl on `the pintle pin 1@ 0 and the pin ends riveted over or otherwise 90 secured in the holes 12 in the hanging leaf. The swinging leaf (Fig. 3) is then set in position with the knuckle stem 19 in the hole 2() and secured therein by meansof the cap nut 22; the hinge then' appears externally as a cranked leaf concealed hinge of the conventional type, the nut being countersunk, not bein a cause of disgurement. Removal of the d setting is, however, readily accomplished by removing the cap nuts 22 and then drawing l the cranked swinging leaves on the knuckle ny fitting or nishingl work required to be done on the door Vmaykthen be accomplished with the greatest facility and 105 the door finally replaced, the hinge' tting oor without disturbing the hinge l- 0 vbeing not at all disturbed :in these oper' ations. L

What I claim as my invention and desire to secure by Letters Patent is:-

1. A concealed door hinge comprising in combination a recessed leaf' adapted to be mounted in a cavity in the door post, said leaf formed with an open side and front and being closed elsewhere, and having a .pintle pin mounted in the recess, a T-stem extending laterally from said pintle,l and a crank leaf having a ilat butt plate adapted to be secured to the inner face of the door stile, there being a socket hole in the crank leaf, said leaf adaptedlto receive the eX- tending portion of said T-stem, and a fixing nut adapted to engage the end of said stem whereby the stem is detachably locked in the crank portion of the crank leaf.

2. In combination in 'ai concealedddor hinge a post'leaf forming a recess and being open at one side and end and closed "else- Where, a pintle pinpivoted Wit-hin said-post leaf and having a lateral extension which is provided on its outer end with a threaded portion, and a crank leaf, said crank leaf provided With. a flat portion adapted tol be secured to the door and to lie in the same general plane therewith and provided with a crank arm extension lying partially in a plane Parallel to that of the Jdoor and partially bent at right angles to such plane, said bent portion being ladapted to be removably secured to the lateral extension of said pin# tle pin.

3. In combination in a concealed door hinge a post leaf forming a recess and bei-ng open at one side and end and closed elsewhere, a pintle pin pivoted within said post leaf and having a lateral extension which -is provided on its outer end 'with a threaded portion, and afcrank leaf, said crank leaf provided with a flat portion adapted .to be secured to the dooiand to lie in the same general plane 'therewith and provided with a crank, arm extension lying partially in -a plane parallel to that of the door' and partially bent at right angles to such plane, said bent portion being. perforated to receivethe lateral extension of said pintle pin and to be removably secured thereon, said l WALTER MORRIS.
